There is a growing need for automated systems that can interview patients and consumers about their health and provide health education and behavior change interventions using natural language dialog. A number of these health dialog systems have been developed over the last two decades, many of which have been formally evaluated in clinical trials and shown to be effective. This article provides an overview of the theories, technologies and methodologies that are used in the construction and evaluation of these systems, along with a description of many of the systems developed and tested to date. The strengths and weaknesses of these approaches are also discussed, and the needs for future work in the field are delineated.
对于能够就健康问题询问患者和消费者，并使用自然语言对话提供健康教育和行为改变干预措施的自动化系统，需求日益增长。在过去二十年中已经开发了许多这样的健康对话系统，其中许多已经在临床试验中进行了正式评估，并证明是有效的。本文概述了用于构建和评估这些系统的理论、技术和方法，同时描述了迄今为止开发和测试的许多系统。还讨论了这些方法的优点和缺点，并阐述了该领域未来工作的需求。
